What does Plan and Spec Mean?

Plan and spec is a method of commercial construction project delivery where design drawings (or plans) are created along with written specifications (or specs) to further describe the equipment and parts shown in the drawings.

The plan and spec method goes by many similar names, like planning and specifications, plan and specifications, plan-spec, or the abbreviated P&S. There are other names for the same method, like design-bid or design-bid-build. These terms are used interchangeably, so you might see us use all different versions here in this article. But don’t be confused – they mean the same thing.

Before a construction project begins, the Owner must decide on the project delivery approach. Plan and spec is the most traditional approach, while newer methods like design-build have been gaining traction. Each project delivery method has its own set of benefits and challenges.  The main difference in methodologies is the alignment of team roles and the timing of construction.
